Fish Misc.

Monkeyface Eel

Pricklebacks: Family Stichaeidae

Species: Cebidichthys violaceus (Girard, 1854); from the Greek cebidichthys (two words meaning Sapajou—a kind of monkey, and fish); and the Latin word violaceus (meaning violet).

Alternate Names: Monkeyface prickleback, blenny eel, monkeyface blenny. Called abrojo cara de mono in Mexico.

Identification: Typical eel shape. Adult fish have a lumpy ridge on the top of the head. Dorsal fin is about half spines and half soft rays. Uniform dull black, olive or gray with 2 darker bars radiating downward from the eye. Some fish have been noted with orange spots on the body or orange at the edge of the fins.


Size: Length to 30 inches. Most caught from piers are 12-24 inches long. The California record was a 6 lb 1 oz fish taken at Pescadero in 2005.

Range: Bahia San Quintin Bay, northern Baja California to southern Oregon; rare south of Point Conception.

Habitat: Intertidal to 80 feet deep; common in shallow rocky areas.

Piers: Generally found at piers in rocky areas or where debris has accumulated at the base of the pier. Best bets: Monterey Coast Guard Pier (the best), Princeton Harbor Pier, Fort Point Pier, San Francisco Municipal Pier, Angel Island Pier and Elephant Rock Pier.

Shoreline: A favorite species for anglers fishing rocky areas and jettys from Point Conception to San Francisco (especially poke polers). Favored areas include Shell Beach (near Pismo Beach), rocks and jetties near the Golden Gate, rocks between Stinson Beach and Muir Beach, rocks between Bodega Bay and Dillon Beach, and rocks north of Crescent City.

Boats: An inshore species rarely take from boats.

Bait and Tackle: Medium tackle; size 4-2 hooks; cut bait (squid), shrimp, pile worms or fresh mussels. The eel’s most common food is crustaceans and algae.

Food Value: Excellent eating.

Comments: Very hard to catch from a pier. Will strike bait and then immediately head back to its rocky lair. Anglers must strike quickly and then keep the pressure on the fish to force it away from the rocks. More commonly caught by “poke poling” in rocky areas along the shoreline.

  1. The picture above is of a Wolf Eel. (also a fish, not really an eel)

  2. No, it’s a monkeyface eel aka monkeyface prickleback, a large monkeyface eel. It is not a wolf eel.
